Abstract
The effects of temperature and strain rate on flow stress of a highly ductile acrylic adhesive were investigated by performing experiments on an adhesively bonded joint at temperatures ranging from 10 to 40℃ at various shear strain rates. The flow stress decreases considerably with decreasing strain rate and with temperature rise. The stress-strain responses under multi-axial stress conditions were also examined by performing combined tension-torsion experiments on the butt-joint. A constitutive model of temperature-dependent elasto-viscoplasticity that describes multi-axial stress-strain behavior of the adhesive is presented.
